Quantum Processes, Systems, and Information
A new and exciting approach to the basics of quantum theory, this undergraduate textbook
contains extensive discussions of conceptual puzzles and over 800 exercises and problems.
Beginning with three elementary “qubit” systems, the book develops the formalism of
quantum theory, addresses questions of measurement and distinguishability, and explores
the dynamics of quantum systems. In addition to the standard topics covered in other
textbooks, it also munication and measurement, quantum entanglement, entropy
and thermodynamics, and quantum information processing.
This textbook gives a broad view of quantum theory by emphasizing dynamical evolution,
and exploring conceptual and foundational issues. It focuses on contemporary topics,
including measurement, time evolution, open systems, quantum entanglement, and the role
of information.
Benjamin Schumacher is Professor of Physics at Kenyon College. He coined the term
“qubit” and invented quantum pression, among other contributions to quantum
information theory.
Michael D. Westmoreland is Professor of Mathematics at Denison University. Trained as
an algebraist, for many years he has researched nonstandard logics, models putation,
and quantum information theory.
The authors are long-time research collaborators and have made numerous joint contri-
butions to quantum channel capacity theorems and other aspects of quantum information
science.
